An electric vehicle power battery waste heat utilization device

Abstract

The invention discloses a power battery waste-heat utilization device of an electric vehicle. The power battery waste-heat utilization device comprises a power battery pack and a temperature difference power generation circuit, and the power battery pack is formed by the fact that battery single bodies which are arrayed in the width direction are in series connection. The side face, which is provided with an electrode connector, on each battery single body is marked as a top end face, and positive electrode connectors and negative electrode connectors on the battery single bodies are arrayed in the width direction. The adjacent battery single bodies are arrayed at intervals, the top end faces of the adjacent battery single bodies are opposite in facing direction, and the positive electrodes or the negative electrodes of the adjacent battery single bodies are adjacent. The temperature difference power generation circuit comprises temperature difference power generation pieces and phase change heat storage materials, the temperature difference power generation pieces are arranged in the gaps between every two adjacent battery single bodies, and the phase change heat storage materials are arranged between the temperature difference power generation pieces and the battery single bodies in a filled mode. The power battery waste-heat utilization device of the electric vehicle has the advantages of being high in efficiency, saving in energy, environmentally friendly, simple in structure, long in service life, stable and reliable in operation and the like. Under the condition that the inside structure of an original power battery pack of the electric vehicle does not need to be changed, the waste heat of the power battery pack is efficiently utilized, and a radiating system of the electric vehicle is improved.

Description

technical field [0001] The invention relates to an electric vehicle power battery waste heat utilization device based on thermoelectric power generation technology. Background technique [0002] As countries around the world pay more and more attention to issues such as energy crisis and environmental pollution, energy conservation and emission reduction has gradually been put on the agenda. Especially in recent years, with the proposal of the energy strategy, saving energy and protecting the environment has become a trend of the times. The gradual deepening of people's knowledge of electricity has provided a strong guarantee for the emergence of electric vehicles. At present, electric vehicles are more and more favored by people because of their advantages of no pollution, no noise, and fuel saving compared with fuel vehicles. However, the development of electric vehicles is also subject to certain bottlenecks. The power of the electric vehicle is provided by the power b...
